Functional endoscopic sinus surgery in a cat with nasal tumor

Abstract

A 11-year-old, 5.8-kg, male European cat was presented with a 4-month history of sneezing, nasal discharge, respiratory distress and bilateral conjunctivitis. Physical examination showed bilateral hemorrhagic mucopurulent nasal discharge and stertorous respiratory sounds. An irregular shaped mass involving the aboral portion of the right nasal cavity and sphenoidal sinus was identified by computed tomography. The mass was localized endoscopically in the medium meatus and an endoscopic-guided biopsy was performed. B-cell lymphoma was diagnosed by histopathological and immunochemistry exams. Functional endoscopic sinus surgery allowed to completely remove the tumor and restore a normal nasal flow. The cat showed no recurrence of the neoplasia for 15 months after the functional endoscopic sinus surgery.
